For businesses operating in the food, pharmaceutical, and cosmetic sectors, securing a reliable supply of high-purity colorants is paramount. Acid Blue 9, scientifically known as Erioglaucine Disodium Salt (CAS 3844-45-9), is a cornerstone ingredient, valued for its vibrant blue hue and excellent stability. As a procurement manager or R&D scientist, understanding the nuances of sourcing this compound, especially from a major manufacturing hub like China, is critical for cost-effectiveness and product quality.

When looking to buy Acid Blue 9, prioritizing suppliers with robust quality control measures is essential. Reputable manufacturers will readily provide Certificates of Analysis (CoA) detailing purity levels, typically specified as ≥85% dye content. Beyond purity, consider the physical form (powder, granule) and solubility, which can impact your formulation process. Engaging with a trusted chemical manufacturer in China offers significant advantages in terms of scale, expertise, and competitive pricing. Many Chinese suppliers specialize in export, streamlining the logistics and documentation required for international trade.

The application of Acid Blue 9 spans a wide range. In the food industry, it's a favored choice for candies, beverages, and baked goods, enhancing visual appeal. For pharmaceutical companies, it serves as a vital colorant in medications, aiding in identification and compliance. The cosmetics industry utilizes it for vibrant shades in personal care items. As you explore purchase options, remember to inquire about minimum order quantities (MOQ) and lead times. Establishing a direct relationship with a primary supplier, rather than going through multiple intermediaries, can often lead to better pricing and more responsive service. Always request samples to test in your specific applications before committing to large orders. By focusing on these key aspects, you can effectively source Acid Blue 9 and ensure the quality and competitiveness of your finished products.
